Hello.
I am using this version:
$ AFNI version info (afni -ver):
Precompiled binary macos_13_ARM_clang: Nov 4 2024 (Version AFNI_24.3.06 'Elagabalus')
When mapping t-values in AFNI, the minimum value in the color bar is cut off and not visible. How can I solve this problem?
I am assuming that the minimum value is probably the same number of the maximum value(just make the maximum value negative), but if there is a better solution, I would appreciate it if you could let me know.
Hi-
Unfortunately, that is something that happens on some OSs.
The minimum value of the color bar is either the negative of the maximum (in your case, the max is 50, hence "-50") or 0. In your case, I can see that it is "-50", based on the top fraction of the numbers peeking/peaking above.
You can control whether the minimum colorbar value of "negative the max" or 0 by selecting the "Pos?" button just below that part of the GUI. By checking the yellow box by "Pos?", that means the colorbar will be positive-only, and hence the colorbar minimum is 0.
No a side note, if you have a dataset output by AFNI, then likely there is internal calculability between p-values and t- or F-stats or correlation values. You can right click on the "p= ..." in the GUI that is in the bottom corner of your image, and select "Set p-value". See here for more details.

Hi, thank you for your reply.
I understand that the minimum value is set to either the negative of the maximum or 0.
I appreciate your help!
